I don't think ceramic pads should be bedded. Semimetallic - yes.
I had a nasty experience with Akebono, after I bedded them - one cool morning right after bedding them, I lost TOTAL braking power. Like pushing the brake pedal as hard as I could, and it seemed like the car had the pedal just for ornament. After this incident I did a research, and it seems that ceramics should NOT be bedded. maybe they form a glazed surface when bedding that will NOT brake at all?
These brake pads, slowly started to bite as time passed. But for about 2 weeks, it was a thrill driving in the city.
